ELEVATOR-BUCKET.

SPECIFICATION forming part of Letters Patent No. 296,008, dated April 1,1884-.

Application filed February 27, 1884. (No model.)

To all whom it may concern.-

Patent No. 290,053 were issued to me Decemher 11, 1883, relates to beltor band elevators such asare used in mills for raising meal, grain, andother substances from one floor or story to another by means of bucketsarranged at suitable distances apart on the band.

The invention described in my patent above referred to consists in abucket open at its bottom, also at its top and mouth or delivery end,but having raised sides andback, said bucket being arranged so that theendless band which carried it formed an inclosure or covering to theopen bottom of the bucket. Buckets so constructed and combined with theband have the advantage of being much lighter than buckets havingbottoms of their own. The samealso have a much quicker emptying actionand admit of the band being run in a nearly vertical course, and do notclog with or carry around a second time the substance being raised. Theylikewise are cheap, durable, and strong, and, being secured on theoutside of the band, they are capable of being readily removed orapplied, as required. The

bucket shown in the accompanying drawings is similar in all the respectshereinbeforenamed to my patented bucket referred to, and

being attached at its back or in its rear to the endless band, whichanswers every purpose for buckets of a certain size, I construct thebucket so that provision is made for attaching it at or near the centerof its lengthor sides to the endless band. This construction andattachment will prevent the buckets,when

of a large size or heavily laden, from pulling away from the band duringthe lift of the buckets. I

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 representsa vertical section of an endless belt and bucketelevator in part, having my improvement applied; and Fig. 2, a

View, as seen from its under side, of one of the buckets detached.

A indicates'the top drum or wheel, in part, of an endless belt andbucket elevator; B, its endless band or belt, in part, traveling asindicated by the arrow w in Fig. 1; and 0 O, certain of its severalbuckets open at their bottoms, tops, and mouths, and having their openbottoms closed or covered by the band, to the outside of which thebuckets, constructed with a back, I), and raised sides 0 c, areattached. These buckets, instead of being secured at their backs or inrear thereof to the band, are fastened at or about the center of theirlength or sides theretoas, for instance, by flanges or projections e eon the inner faces of the sides of the bucket in proximity to the. band,and short bolts d d, arranged to pass through said flanges and the band.Thus secured at or about their centers to the band, said buckets, whenof a large size or heavily laden, will not,

This is important, considering that the band constitutes the bottoms ofthe buckets.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In buckets of endless belt or band elevators,having open bottoms and raised sides and back, the bucket constructed orprovided with means for attaching it in front of its back, at or nearthe center of the length of its sides, to the exterior of the band,substantially as and for the purpose herein set forth.

2. In endless belt and bucket elevators, the combination, with theendless belt B, of the buckets O, constructed i with a back, I), andsides 0 0, but left open at their tops, bottoms, and mouths or deliveryends, and attached at or near the center of the length of their sides,in front of their backs, to the outside of the belt or band,substantially as shown and described.
